fix: ignoreNoDocuments option usage when using graphql configs

[Axxxx0n]

Description

When using general graphql configs (eg. graphql.config.json) instead of codegen configs (eg. codegen.ts), ignoreNoDocuments option and CLI flag are not working. Additional guard was added when loading documents to not throw error when ignoreNoDocuments option is needed.
